      perf bpf: Rename 'cpu' to 'cpu_map_idx' · 7263f349
      Ian Rogers authored
      Synchronize the caller in evsel with the called function.
      
      Shorten 3 lines of code in bperf_read by using
      perf_cpu_map__for_each_cpu().
      
      This code is frequently using variables named cpu as cpu map indices,
      which doesn't matter as all CPUs are in the CPU map. It is strange in
      some cases the cpumap is used at all.
      
      Committer notes:
      
      Found when building with BUILD_BPF_SKEL=1:
      
      Remove unused 'num_cpu' variable in bperf__read().
      
      Make 'j' an 'int' as it is used in perf_cpu_map__for_each_cpu() to compare against an 'int'

      perf evlist: Refactor evlist__for_each_cpu() · 472832d2
      Ian Rogers authored
      Previously evlist__for_each_cpu() needed to iterate over the evlist in
      an inner loop and call "skip" routines. Refactor this so that the
      iteratr is smarter and the next function can update both the current CPU
      and evsel.
      
      By using a cpu map index, fix apparent off-by-1 in __run_perf_stat's
      call to perf_evsel__close_cpu().

      Passing the number of CPUs and threads allows for an evsel's counts to
      be mismatched to its cpu map. To avoid this always derive the counts
      size from the cpu map. Change openat-syscall-all-cpus to set the cpus
      to allow for this to work.

      perf cpumap: Add CPU to aggr_cpu_id · 34794913
      Ian Rogers authored
      With no aggregration, such as 'perf stat -A', the aggr_cpu_id lacks a
      way to describe per CPU aggregation and the core is set to the CPU in
      places like print_counter_aggrdata in stat-display.c.
      
      Setting the core to the CPU is undesirable as the CPU will exceed valid
      core values and lead to confusion. Add a CPU variable to address this.

      perf cpumap: Switch cpu_map__build_map() to cpu function · eff54c24
      Ian Rogers authored
      Avoid error prone cpu_map + idx variant. Remove now unused functions.
      
      Committer notes:
      
      Remove by now unused perf_env__get_cpu().
